Here, we explore how Lantech Communications’ solutions are resolving challenges for the future intelligent traffic system.
What are the challenges for intelligent transport communication systems?
Intelligent transport systems (ITS) cover several different technologies and applications, from basic management systems, such as traffic signal control systems and monitoring applications like security CCTV systems, through to more advanced applications that integrate big data, including parking guidance and information systems. All of these applications rely on a consistent data communication system.
In ITS environments, no matter where the devices are installed, they must be able to withstand harsh operating conditions that include vibration, shock, input voltage ripple, and surge. Looking for more sustainable and cost-efficient solutions to connect all communications systems becomes the top priority for all operators.
Lantech was chosen by major operators globally
Lantech Communications Australia is headquartered in Perth, Western Australia, and is a joint venture partner of Taiwan-based Lantech Global, which provides the networking (switch and router) infrastructure for these communications systems.
According to Lantech Communications sales VP, Amanda Lee, Lantech’s vehicle solutions are adopted on buses across the world, including French operator Keolis’ networks as well as the transportation systems in Slovenia and Spain, and by Israel’s leading bus manufacturer Merkavim.
Embedded DC-DC conversion for PoE applications within a rugged house
Lantech’s superior high frequency power conversion circuits are one of the reasons that Lantech’s solution was chosen over its competitors. These circuits inside the switches themselves allow for DC-DC conversion into regulated 54VDC voltages for Power over Ethernet (PoE) operation.
“As all these devices are IP-based and digitalised, the system integrators wanted to use our switches. They wanted the switches to not only be able to provide the data communications but also to have the PoE functionality, which eliminates the need to have additional power for each device, which is more convenient,” Ms Lee said.
Lantech is capable of providing DC-DC conversion technology inside the switches to handle the direct input power. For the 24 volts that is commonly seen on vehicles, the switch can boost within the switch system to feed the power over the Ethernet and comply with the PoE 802.3at standard.
“Because we can handle the DC-DC conversion and can make it in smaller housing and with much better support, our customers choose us over our competitors,” Ms Lee said.
More rugged and sustainable to meet international standards
For Lantech, it is not enough to design its offerings with rugged parts, with certifications from trusted organisations also proving that its products are suitable for ITS applications.
“The E-mark is an EU mark issued by the Economic Commission of Europe for approving vehicles and vehicle components sold in the EU, our routers and switches passed several critical EMI/EMS tests to get the certifications. We are able to provide the most sustainable products that meet the high standards of Europe,” Ms Lee said.
Lantech is also a member of the Belgium-based non-profit association Information Technology for Public Transport Association (ITxPT). This international association of public transport works towards standardising technical solutions within public transportation.
“As an ITxPT member and a key supplier to the mass/public transportation industry, we have access to the ITxPT platform for testing our wide range devices in real operational conditions,” Ms Lee said.
“This supports the adoption of plug-and-play systems by limiting the risks associated with the integration stage and helping increase reliability, while improving cost-effectiveness as well.”
10G uplink for increasing demand of bandwidth
The wireless applications and high-definition cameras increase the demand of bandwidth, which means that the rising needs of 10G – referring to internet speeds of 10 gigabits per second – is one of the challenges Ms Lee says Lantech is overcoming.
“Since 10G is so fast, the heat generated is a lot higher, so it’s very easy to overheat. Also, you have to put the DC-DC conversion inside the switches. That’s why there are very few competitors who offer such a compact yet high port 10G uplink switches on the market, because you need to resolve the problem of heat dissipation.”
Wireless solutions for ITS
The company is undergoing an exciting period. Aside from being in a leading position with its offerings, Lantech also launched a series of routers which integrate a lot of the functionality that covers PoE, LTE, Wi-Fi, VPN, managing switches functions, and Modbus gateway.
“We come from a background of switches, so that’s where we have some of the most interesting product ranges for new solutions,” Ms Lee said.
Within these router solutions, Lantech is always adding more and more features. One of the latest developments is InstaAir, a cloud-based fleet management system for routers, allowing over-the-air device monitoring, configuration, and software upgrades anytime, anywhere.
